All silicon transistors have the same dependency on temperature, there's nothing youcan do by choosing a better device.

What you can do is use a cancelling circuit to subtract the temperature dependence byusing two matched transistors kept at the same temperature. You keep a constant current through one and then the Vbe difference cancels out.

You can also choose a semiconductor with a much higher bandgap voltage, as thethermal term subtracts from this, so the larger the bandgap the less the thermalterm proportionally. That means gallium arsenide, silicon carbide or other exotic/expensivedevices.

But unless you say what you are trying to achieve its hard to know how to help.The cancellation circuit is useful for making analog logarithmic amplifiers andmultipliers, for instance.

It might be that you need feedback in your circuit to linearise it, there are many waysround a problem if you know the actual goal.

That's good, because unless you describe it in more detail - in fact a lot more detail, explanation and specifics including current and proposed circuitry - you are not going to get much useful assistance.
